Thanks for the insights. I didn't realize that the glowing ends of the
bulb, which I have seen many times, spelled failure. That will save me
quite a bit in the coming years so I appreciate the info.
Arcade games have a small fluorescent fixture in them and sometimes
these games sit in locations for years with the bulb burned out. When
I would go to replace the bulb the new one would just not start at all
and then when I would try and place the same bulb in a new fixture it
would also be dead. Can you measure the voltage on the fixture to
check and see if it is within specs? What would you look for? Or can
you with the power off check the ballast with the OHM settings on a DVM
to see if there are shorts? And the same with the starter, is there a
way to check it to see if it is the culprit? And... I am sorry about
all of the questions but I have been meaning to fill in this missing
knowlege for quite some time, how do you check a bulb to see if it is
ok? Is putting it in a known working fixture the only way?
I was working on a regular fluorescent fixture that lit a display
counter in a store . When I placed a bulb in the fixture it lit up and
I thought it was fine but it went out within a minute and when I
touched the bulb it was really hot. There was no starter on this
fixture. I don't know much about these things. What might have been
happening with this one? And like in my above question can you check
it with a DVM to see if it is OK before inserting the bulb? The bulb
costs almost as much as the fixture.
Thanks for the help I really appreciate it.
